The App Store has its share of endless-running games, but we’re always down for one more, especially if it comes with a mountain of content. Such is the case with Rock Runners, a thoroughly entertaining gem from Chillingo that has more than 140 bite-sized stages that will definitely appeal to platform fanatics.

Set in the distant future, Rock Runners puts gamers in control of a death-defying runner traveling from point A to point B. Controls couldn’t be simpler, as players tap the screen to jump, and that’s about all they’ll have to do, which means the game is ideal for people of all skill levels.

Each board is an obstacle course filled with hazards, including drills that erupt from the ground, falling rocks, toxic sludge, and enemy robots, to name several. Timing is especially key, since gamers must keep the helmet-wearing hero pushing forward without taking damage or getting stuck.

Fortunately, objects within the environment will help him survive, starting with grapple points. As the character sails through the air, players press and hold the screen to activate the runner’s grappling device, allowing him to swing to safety. On top of that, players will encounter moving platforms to avoid the aforementioned goop, and portals (perhaps a nod to Valve’s Portal games) that transport the runner to new areas.

All the while, gamers will need to keep an eye out for collectibles, primarily keys that unlock new stages and gems to spend at the in-game store, filled with items designed to give them an edge. Of key importance, a Gem Magnet that attracts those precious stones, a Power Shield to protect the runner from danger, and three different characters.

Granted, an endless mode would have been appreciated, just to see how far we could travel before wiping out, but in its current form, Rock Runners is a delight. The sheer number of levels, unlocked goodies, and cool outer space theme should keep players busy for hours. With downloadable content on the way, we think this title will be a favorite for weeks to come.
